Use of IRS, RS and GIS Data to Estimate EPM Parameters Case Study: Tange Bostanak Watershed. E.E.R. . 2013; 2 (4) :35-48
Abstract:   (3522 Views)

The use of new methods, remote sensing (RS) and geographical information system (GIS) in zoning the water erosion in a particular geographical area (Tang-e-Bostanak catchment area) constitute the main subjects of this study. The production, combination, and composition of effective information layers in identifying these zones have been noted, highlighting the capacity of GIS and RS. In this study the erosion and sediment rates of Tange Bostanak watershed have been estimated according to the EPM method. In this model environmental factors were studied with RS and GIS. In the EPM model the yearly specific erosion rate was 1174.89 and the sediment yield rate was 869.41. There have been high, medium, and very high erosion risks of 58.9, 40.92 and 0.21 percent of the basin area, respectively. The results indicate that the EPM model with use of RS and GIS is acceptable in estimating erosion and sediment.
